D1K vs EDC2-DFT: how they differ
Size and weight
The Emisar D1K is the shorter light: 114 mm (4.49 in) against 150 mm (5.91 in), a difference of 36 mm (24%). At its widest point the SureFire EDC2-DFT is 3 mm slimmer (32 vs 35 mm). Weights are published on different bases (Emisar D1K: 89 g without battery; SureFire EDC2-DFT: 159 g listed), so they are not directly comparable.
Brightness and throw
The Emisar D1K is rated brighter: 1,200 lm maximum vs 700 lm for the SureFire EDC2-DFT, 71% more.
Battery
The Emisar D1K runs on a removable 21700 battery; the SureFire EDC2-DFT runs on a removable 18650 battery. For scale, a 21700 cell is about 21 × 70 mm and a 18650 about 18 × 65 mm (nominal).
Price
When we checked on Nov 4, 2026, the Emisar D1K was $39.95 at intl-outdoor.com and the SureFire EDC2-DFT from $287.00 at batteryjunction.com, so the Emisar D1K cost $247.05 less. Prices change often, so check the current price before you buy.
Type
Both are EDC lights in our catalog with a tube body.
Which should you buy?
Choose the Emisar D1K if you want a shorter light (36 mm shorter) and more output (1,200 lm vs 700 lm). Choose the SureFire EDC2-DFT if you want a slimmer profile (3 mm narrower). We compare published size, weight, output, throw and battery only, not runtime, interface or build quality.
